Description

Technical Field

[0001] This utility model relates to a mechanism for preventing excessive tension on the barrel of a mobile filling device in an automobile assembly line, belonging to the field of mobile filling technology in automobile production lines. Background Technology

[0002] In mobile refueling equipment on automotive assembly lines, barrel anti-pull mechanisms are used to prevent damage to the barrel due to excessive tension. Traditional barrel anti-pull mechanisms typically employ a mechanical structure; when the barrel is subjected to tension, a mechanical device triggers a protective mechanism to stop the barrel's movement. However, this structure has the following drawbacks:

[0003] The inability to adjust acceleration and deceleration based on the barrel's tension state can easily lead to production line shutdowns and affect production efficiency.

[0004] The barrel is usually fixed vertically or horizontally, which puts it under great force and makes it difficult to trigger the anti-pull alarm. Moreover, the pulling force when the alarm is triggered is large and may damage the vehicle's oil reservoir. Utility Model Content

[0005] This invention addresses the shortcomings of existing barrel anti-pull technology in mobile refueling equipment by providing a simple, reliable, and easy-to-maintain barrel anti-pull device for mobile refueling equipment, thereby solving the aforementioned problems.

[0006] The anti-pull device for the barrel of the mobile refueling equipment of this utility model adopts the following technical solution.

[0007] The anti-pull device includes a support frame, a slide rail, and a barrel clamp. The slide rail is mounted on the support frame, and a barrel clamp fixing plate is installed on the slide rail via a slider. The barrel clamp is fixedly installed on the barrel clamp fixing plate. A limit switch trigger plate and a proximity switch trigger plate are installed on the barrel clamp fixing plate. The support frame is equipped with a forward safety anti-pull switch, a rearward safety anti-pull switch, a forward proximity switch, and a rearward proximity switch.

[0008] The support frame consists of support rods on both sides and connecting plates. The support rods are connected to both sides of the connecting plates via anti-tension fixing plates. The slide rail is mounted on the connecting plates. The anti-tension fixing plates are provided with angle adjustment slots to adjust the installation angle of the connecting plates. The slide rail can change angle with the connecting plates, causing the barrel clamp fixing plate and barrel clamp on the slide rail to be in an inclined state.

[0009] The barrel clamp fixing plate is tilted backward relative to the vertical direction on the slide rail, and the barrel clamp installed on it is also tilted, with the tilt direction consistent with the direction of the filling pipe when filling. The barrel clamp fixing plate is used to fix the barrel at an angle to reduce the stress on the barrel, reduce the pulling force value when the barrel triggers the anti-pull alarm, and avoid damage to the vehicle's oil can.

[0010] The barrel clamp fixing plate is mounted on the slide rail via a slider. The slider drives the barrel clamp fixing plate and the barrel clamp to move on the slide rail, which is used to transmit the tension state of the barrel.

[0011] The forward safety anti-pull switch and the backward safety anti-pull switch are located on both sides of the limit switch trigger plate, and are used to trigger the protection mechanism when the gun barrel is stretched to the limit position.

[0012] The forward proximity switch and the backward proximity switch are located on both sides of the proximity switch trigger plate, respectively, and are used to detect the extension direction and degree of the barrel, so as to realize the acceleration and deceleration function of the moving refueling equipment.

[0013] The support frame is equipped with a clamp guide mechanism, which includes a guide rod, linear bearings, and an anti-pull moving block. The guide rod is mounted on two linear bearings, which are fixedly mounted on a linear bearing fixing plate. The linear bearing fixing plate is connected to the support frame. The anti-pull moving block is connected to the guide rod and also to the barrel clamp fixing plate. As the barrel clamp fixing plate moves on the slide rail, the guide rod moves along with it via the anti-pull moving block, thus guiding the movement of the barrel clamp. The guide rod moves within the linear bearings.

[0014] The guide rod is equipped with an automatic reset mechanism, which uses a spring. The spring is mounted on the guide rod and positioned between the anti-pull moving block and the linear bearing. When the barrel clamp moves, the anti-pull moving block moves along with it and compresses the spring, thus providing a buffering effect.

[0015] The entire mechanism is connected to the mobile dispensing equipment via a support frame, securing the barrel on the mobile dispensing equipment to the barrel clamp. When the barrel is subjected to a forward pulling force, the barrel clamp moves forward along the slide rail, triggering a forward proximity switch. Upon receiving the signal from the forward proximity switch, the mobile dispensing equipment accelerates its movement to reduce the pulling force on the barrel. When the barrel is subjected to a backward pulling force, the barrel clamp moves backward along the slide rail, triggering a backward proximity switch. Upon receiving the signal from the backward proximity switch, the mobile dispensing equipment stops moving to prevent further stretching of the barrel. When the barrel is stretched forward to its limit, a forward safety pull-back switch is triggered, stopping the mobile dispensing equipment and halting the production line. When the barrel is stretched backward to its limit, a backward safety pull-back switch is triggered, similarly stopping the mobile dispensing equipment and halting the production line.

[0016] This invention features a simple structure, high reliability, and easy maintenance. It enables mobile refueling equipment to accelerate and decelerate based on the tension state of the nozzle, reducing unnecessary production line downtime and improving production efficiency. The nozzle is fixed at an angle, aligning with the pipe direction during refueling, reducing the stress on the nozzle and lowering the tension value when the anti-pull alarm is triggered, thus preventing damage to the vehicle's oil reservoir.

[0022] The present invention relates to a barrel anti-pull device for mobile refueling equipment, the structure of which is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a support frame, a slide rail 4, and a barrel clamp 3.

[0023] The support frame consists of support rods 1 on both sides and connecting plates 12. The support rods 1 are connected to both sides of the connecting plates 12 via anti-tension fixing plates 2. The support rods 1 are connected to the mobile filling equipment. The anti-tension fixing plates 2 are provided with arc-shaped angle adjustment slots 18. The connecting plates 12 are fastened to the anti-tension fixing plates 2 via bolts in the angle adjustment slots 18. The bolts extend from the angle adjustment slots 18 into the threaded holes on the anti-tension fixing plates 2. After adjusting the angle of the connecting plates 12, the bolts are tightened. The angle adjustment slots 18 facilitate the adjustment of the angle of the connecting plates 12.

[0024] The slide rail 4 is mounted on the connecting plate 12 and can change angle with the connecting plate 12. A barrel clamp fixing plate 10 is mounted on the slide rail 4 via a slider 5, and the barrel clamp 3 is fixedly mounted on the barrel clamp fixing plate 10 (see...). Figure 2 The barrel clamp 3 can move on the slide rail 4 via the barrel clamp fixing plate 10 and the slider 5. The slider 5 is mounted on the slide rail 4 and connected to the barrel clamp fixing plate 10 to transmit the tension state of the barrel.

[0025] By changing the angle of the connecting plate 12, the slide rail 4 is tilted backward relative to the vertical direction (see...). Figure 2 and Figure 3 This causes the barrel clamp fixing plate 10 and the barrel clamp 3 to be tilted backward, with the tilt direction consistent with the direction of the filling pipe during the filling process. The barrel clamp fixing plate 10 is used to fix the barrel at an angle, consistent with the direction of the barrel during the filling process, in order to reduce the stress on the barrel, lower the pulling force value when the barrel triggers the anti-pull alarm, and avoid damage to the vehicle's fuel tank.

[0026] Limit switch trigger plate 7 and proximity switch trigger plate 9 are fixedly installed on the barrel clamp fixing plate 10.

[0027] A forward safety pull switch 6 and a backward safety pull switch 16 are fixedly installed on the connecting plate 12 of the support frame. These switches are used to trigger a protection mechanism when the barrel is stretched to its limit position, stopping the movement of the refueling equipment and halting the line to protect the barrel and equipment. The forward safety pull switch 6 and the backward safety pull switch 16 are located on both sides of the limit switch trigger plate 7.

[0028] A forward proximity switch 8 and a backward proximity switch 15 are fixedly installed on the connecting plate 12 of the support frame. These switches are configured to trigger the forward and backward tracking detection switches, respectively, to detect the direction and extent of barrel extension, thus enabling the acceleration and deceleration functions of the mobile refueling device. The forward proximity switch 8 and the backward proximity switch 15 are located on opposite sides of the proximity switch trigger plate 9. When the forward proximity switch 8 is triggered, the mobile refueling device accelerates to reduce the tension on the barrel. After detecting no signal from this switch, the mobile refueling device resumes normal forward speed. When the backward proximity switch 15 is triggered, the mobile refueling device stops moving to prevent further extension of the barrel. After detecting no signal from this switch, the mobile refueling device resumes normal forward speed.

[0029] A clamp guide mechanism is provided on the support rod 1. This guide mechanism includes a guide rod 14, linear bearings 11, and an anti-pull moving block 13. The guide rod 14 is mounted on two linear bearings 11, which are fixedly mounted on a linear bearing fixing plate 17. The linear bearing fixing plate 17 is fixedly mounted on the connecting plate 12 of the support frame. The guide rod 14 can move within the linear bearings 11. The anti-pull moving block 13 is connected to the guide rod 14 and to the barrel clamp fixing plate 10. As the barrel clamp fixing plate 10 and the barrel clamp 3 move on the slide rail 4, the guide rod 14 moves along with them via the anti-pull moving block 13, thus guiding the movement of the barrel clamp 3.

[0030] An automatic reset mechanism is provided on the guide rod 14. This mechanism uses a spring (not shown in the figure). The spring is located on the guide rod 14 and between the anti-pull moving block 13 and the linear bearing 11. Springs are also provided between the anti-pull moving block 13 and both linear bearings 11. When the barrel clamp 3 moves, the anti-pull moving block 13 moves accordingly and compresses the spring, thus providing a buffering effect. The ends of the two guide rods contact the anti-pull moving block 13. The left and right movement and automatic reset of the anti-pull mechanism are realized through the spring, the guide rod 14, and the anti-pull moving block 13.

[0031] The operation process of the barrel anti-pull device of the aforementioned mobile refueling equipment is as follows.

[0032] The barrel on the mobile refueling device is clamped and fixed on the barrel clamp 3, and the entire mechanism is connected to the mobile refueling device through the support rod 1.

[0033] When the barrel is subjected to a forward pulling force, the slider 5 moves forward along the slide rail 4, triggering the proximity switch 8. Upon receiving the signal from the forward proximity switch 8, the mobile refueling device accelerates to reduce the pulling force on the barrel. Once the pulling force on the barrel disappears, the forward proximity switch 8 stops outputting a signal, and the mobile refueling device resumes its normal forward speed.

[0034] When the barrel is subjected to a backward pulling force, the slider 5 moves backward along the slide rail 4, triggering the backward proximity switch 15. Upon receiving the signal from the backward proximity switch 15, the mobile refueling device stops moving to prevent the barrel from being further stretched. When the pulling force on the barrel disappears, the backward proximity switch 15 outputs no signal, and the mobile refueling device resumes its normal forward speed.

[0035] When the barrel is extended forward to its limit position, the forward safety anti-pull switch 6 is triggered, stopping the movement of the mobile dispensing equipment and halting the production line. When the barrel is extended backward to its limit position, the backward safety anti-pull switch 16 is triggered, similarly stopping the movement of the mobile dispensing equipment and halting the production line.
